"Forward's book is a knockout. In science fiction there is only a handful of books that stretch the mind--and this is one of them"--Arthur C. Clarke
Start with a neutron star, one of the densest things known to man, send humans out to investigate it, discover life on it (under heavier gravity than you could ever imagine with lifes measured in seconds rather than years), and sit back and read what happens - I couldn't put this book down.
It's better than Isaac Asimov, Larry Niven and Arthur C. Clarke all rolled into one.
I hope that they re-release the sequel as well "Starquake".
Just a quick word of warning - this is not a new book - it was released originally 20 years ago and the sequel 15 years ago. The story doesn't date, but just check to make sure it's not already in your collection.
Amazing that this book has hardly dated in 20 years.
